Looking for recs on fully mechanical keyed doorknobs

12. If you want a top shelf deadbolt for the door, get a Medeco.

The Medeco will be stronger than the door and hinges and will last a lifetime. I recently replaced my entry locks with a digital system. No key to hide, program any code that makes you happy, change it when you need to.

I used moderately priced, Quikset locks because, no matter how strong my door is, my windows are all glass...Security is not a lock, it is a system.
